I can compare pins of HSMC connector on p13 of DE2-115 schematics (am I on the wrong page?)

Yes, I meant p13, sorry.
I've attached the schematic from the DE2_115_v.1.0.5_SystemCD so you have the same version.

I can compare pins of HSMC connector on p13 of DE2-115 schematics (am I on the wrong page?) with the ones of the male HSMC connector provided by the TI adapter: every pin on the TI board is also on the female HSMC on the DE2-115.

Ok thats a good start. Why don't you post the TI EVM schematic PDF, or post a link to the PDF on TI's web site.

Now, if I got what you said I have to verify if all of these pins come to the FPGA: the only ones I can't find on p25 are HSMC_SDA and HSMC_SCL. Are they the high-speed "trainscever lanes" you were referring to? (sorry, I'm a complete beginner with this kind of problems)

No. These are I2C connections. If the TI kit does not use them, its no problem.

Anyway, if they are I can read on DE2-115 User Manual that "Signals HSMC_SDA and HSMC_SCLK share the same bus with the respected signals I2C_SDA and I2C_SCL of the WM8731 audio chip": I looked for them on DE2-115 schematics and they're found on the Bank 8. Am I missing something?

So long as the TI kit does not short these pins to ground, the DE115 I2C bus will work fine.

About the second answer you gave, I need to think a bit longer about it before probably asking some more =)

No problem. Ask questions when you are ready.
